module ActiveJob::TestHelper

Provides helper methods for testing Active Job

Public Instance Methods

after_teardown() Show source 
# File activejob/lib/active_job/test_helper.rb, line 17
def after_teardown
  super
  ActiveJob::Base.queue_adapter = @old_queue_adapter
end
Calls superclass method
assert_enqueued_jobs(number) { || ... } Show source 
# File activejob/lib/active_job/test_helper.rb, line 45
def assert_enqueued_jobs(number)
  if block_given?
    original_count = enqueued_jobs.size
    yield
    new_count = enqueued_jobs.size
    assert_equal number, new_count - original_count,
                 "#{number} jobs expected, but #{new_count - original_count} were enqueued"
  else
    enqueued_jobs_size = enqueued_jobs.size
    assert_equal number, enqueued_jobs_size, "#{number} jobs expected, but #{enqueued_jobs_size} were enqueued"
  end
end

Asserts that the number of enqueued jobs matches the given number.

def test_jobs
  assert_enqueued_jobs 0
  HelloJob.perform_later('david')
  assert_enqueued_jobs 1
  HelloJob.perform_later('abdelkader')
  assert_enqueued_jobs 2
end

If a block is passed, that block should cause the specified number of jobs to be enqueued.

def test_jobs_again
  assert_enqueued_jobs 1 do
    HelloJob.perform_later('cristian')
  end

  assert_enqueued_jobs 2 do
    HelloJob.perform_later('aaron')
    HelloJob.perform_later('rafael')
  end
end
assert_enqueued_with(args = {}) { || ... } Show source 
# File activejob/lib/active_job/test_helper.rb, line 158
def assert_enqueued_with(args = {}, &_block)
  original_enqueued_jobs = enqueued_jobs.dup
  clear_enqueued_jobs
  args.assert_valid_keys(:job, :args, :at, :queue)
  serialized_args = serialize_args_for_assertion(args)
  yield
  matching_job = enqueued_jobs.any? do |job|
    serialized_args.all? { |key, value| value == job[key] }
  end
  assert matching_job, "No enqueued job found with #{args}"
ensure
  queue_adapter.enqueued_jobs = original_enqueued_jobs + enqueued_jobs
end

Asserts that the job passed in the block has been enqueued with the given arguments.

def test_assert_enqueued_with
  assert_enqueued_with(job: MyJob, args: [1,2,3], queue: 'low') do
    MyJob.perform_later(1,2,3)
  end
end
assert_no_enqueued_jobs(&block) Show source 
# File activejob/lib/active_job/test_helper.rb, line 77
def assert_no_enqueued_jobs(&block)
  assert_enqueued_jobs 0, &block
end

Asserts that no jobs have been enqueued.

def test_jobs
  assert_no_enqueued_jobs
  HelloJob.perform_later('jeremy')
  assert_enqueued_jobs 1
end

If a block is passed, that block should not cause any job to be enqueued.

def test_jobs_again
  assert_no_enqueued_jobs do
    # No job should be enqueued from this block
  end
end

Note: This assertion is simply a shortcut for:

assert_enqueued_jobs 0, &block
assert_no_performed_jobs(&block) Show source 
# File activejob/lib/active_job/test_helper.rb, line 147
def assert_no_performed_jobs(&block)
  assert_performed_jobs 0, &block
end

Asserts that no jobs have been performed.

def test_jobs
  assert_no_performed_jobs

  perform_enqueued_jobs do
    HelloJob.perform_later('matthew')
    assert_performed_jobs 1
  end
end

If a block is passed, that block should not cause any job to be performed.

def test_jobs_again
  assert_no_performed_jobs do
    # No job should be performed from this block
  end
end

Note: This assertion is simply a shortcut for:

assert_performed_jobs 0, &block
assert_performed_jobs(number) { || ... } Show source 
# File activejob/lib/active_job/test_helper.rb, line 112
def assert_performed_jobs(number)
  if block_given?
    original_count = performed_jobs.size
    perform_enqueued_jobs { yield }
    new_count = performed_jobs.size
    assert_equal number, new_count - original_count,
                 "#{number} jobs expected, but #{new_count - original_count} were performed"
  else
    performed_jobs_size = performed_jobs.size
    assert_equal number, performed_jobs_size, "#{number} jobs expected, but #{performed_jobs_size} were performed"
  end
end

Asserts that the number of performed jobs matches the given number. If no block is passed, perform_enqueued_jobs must be called around the job call.

def test_jobs
  assert_performed_jobs 0

  perform_enqueued_jobs do
    HelloJob.perform_later('xavier')
  end
  assert_performed_jobs 1

  perform_enqueued_jobs do
    HelloJob.perform_later('yves')
    assert_performed_jobs 2
  end
end

If a block is passed, that block should cause the specified number of jobs to be performed.

  assert_performed_jobs 1 do
    HelloJob.perform_later('robin')
  end

  assert_performed_jobs 2 do
